The Centre for Health Protection, a branch of the Department of Health, recently made an announcement about the number of dengue fever (DF) cases located in Hong Kong.

The announcement included encouragement to sustain strict mosquito control, environmental hygiene, and personal protective measures when traveling outside of Hong Kong.

"As the dengue activity in southern Taiwan remains high, the public are reminded to take anti-mosquito measures when travelling to the area, and to Southeast Asian countries, in order to prevent DF," a CHP spokesman said.

Between Oct. 23 and 29, there were another five dengue fever cases recorded. All of these cases were imported, and the patients had recently traveled to Thailand (two cases), the Mainland (two cases), and Vietnam (one case) throughout the incubation period.

As of Thursday, there have been 95 dengue fever cases for 2015. These include one local case, one unclassified case, and 92 imported cases. This is the highest number of dengue fever cases compared to recent decades. There were 22 to 95 cases each year from 2005 to 2014.

"Dengue viruses encompass four different serotypes,” a CHP spokesman said. “The symptoms of first infection with one serotype are usually mild, but subsequent infections with other serotypes even years afterward are more likely to result in severe dengue, also known as dengue haemorrhagic fever. Severe dengue is serious and potentially fatal. Without proper treatment, the case fatality rate of severe dengue can exceed 20 percent.”
